OEM Carrier Flame Sensor (48GS400192) for Model PY1PEB048130ABAA

This is the factory OEM replacement flame sensor for the Carrier PY1PEB048130ABAA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification technology to verify a burner flame is present during each heating cycle. When the burner ignites, the flame produces a small microamp electrical signal through the rod; the control board reads this signal to confirm combustion. A failed or contaminated flame sensor causes the furnace to light briefly, then shut down on safety lockout after just 5–8 seconds — one of the most common furnace service calls in the field.

• Part Number: 48GS400192 | 90-degree flame sensor with mounting bracket | Factory-spec rod length and geometry for precise fit in the PY1PEB048130ABAA burner assembly
• OEM vs Generic: This is a genuine Carrier OEM part — not an aftermarket clone. OEM sensors are manufactured to exact rod alloy and geometry specifications. Generic sensors often exhibit reduced microamp output, leading to nuisance lockouts and premature failure.
• Install Difficulty: 2/5 — A straightforward swap once access panels are removed. Tools needed: 1/4" nut driver, small flat-head screwdriver, fine steel wool or emery cloth (to clean rod if reusing), multimeter to verify microamp output post-install. Always disconnect power before servicing.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders ship same business day from our warehouse.
